   I am getting an error from my blog site http://www.misustainable.com/blog/. I have not changed it and now the site won't display and gives this error:

   Warning: Cannot modify header information - headers already sent by (output started at /home/content/s/u/s/sustainablewm/html/blog/wp-content/plugins/wordpress-automatic-upgrade/wpau_helper.class.php:205) in /home/content/s/u/s/sustainablewm/html/blog/wp-includes/pluggable.php on line 850

   I tried to bypass the home page and login as admin and I can get the login screen but it shows the same error twice but on two different lines now.

   How can I fix this? Do I reinstall? Will I loose everything if I do?

   login via FTP and delete the offending plugin - wordpress-automatic-upgrade.

   With 2.7 it shouldn't be needed.

   I did that now it has issues with the theme I am using. The main page will display but when I go to login as admin it gives me this:

   Warning: Cannot modify header information - headers already sent by (output started at /home/content/s/u/s/sustainablewm/html/blog/wp-content/themes/atahualpa/functions/bfa_search_widget.php:41) in /home/content/s/u/s/sustainablewm/html/blog/wp-login.php on line 255

   Do I delete the theme and reinstall it?

   Elfin thanks for your help but I seem to be getting more errors now.

   Now when I login I see these errors. At least they are not the same as before, but still not letting me in.

   It's not your theme (probably) but the plugin didn't upgrade you properly.

   Re-download WordPress and upgrade manually.

   Thanks for your help Ipstenu. I did the manual upgrade but I am still getting this error when I go to the blog homepage:

   Warning: Cannot modify header information - headers already sent by (output started at /home/content/s/u/s/sustainablewm/html/blog/wp-content/themes/atahualpa/functions/bfa_search_widget.php:41) in /home/content/s/u/s/sustainablewm/html/blog/wp-includes/pluggable.php on line 850

   And I can only see the blog homepage if I take the www away from the url. Like this: http://misustainable.com/blog/ Instead of http://www.misustainable.com/blog/

   And when I try to login I get the login screen with errors at the top again:

   Warning: Cannot modify header information - headers already sent by (output started at /home/content/s/u/s/sustainablewm/html/blog/wp-content/themes/atahualpa/functions/bfa_search_widget.php:41) in /home/content/s/u/s/sustainablewm/html/blog/wp-login.php on line 255

   And then it takes me to a page full of errors:

   Warning: Cannot modify header information - headers already sent by (output started at /home/content/s/u/s/sustainablewm/html/blog/wp-content/themes/atahualpa/functions/bfa_search_widget.php:41) in /home/content/s/u/s/sustainablewm/html/blog/wp-login.php on line 255

   I am not sure what else to do. I was thinking it may be the theme but I can't login to change it. I tried deleting it and reinstalling it, but no difference there either.

   If you delete the theme I think WP will use a default one. By deleting and reinstalling you haven't actually done anything of any use (sorry).

   Open up your wp-config.php, ensure that there is no whitespace before the <?php, or after the ?>

   re-upload it and see if that helps.

   Thank you so much elfin! I want to give you a big kiss! There was a space and a blank line after it. I don't understand how because that was one of the files that supposedly was not changed in the upgrade...

   THANK YOU AGAIN! YOU JUST MADE MY DAY!
